Hi, Also, keep in mind that, with the code you`re using, you`re creating empty wikis. In practice, when using (copying) a template or a flavour/extension (future feature done with the Extension Manager), your wiki creation times will grow considerably. Basically all you are testing now is the creation of databases and a document (the wiki descriptor). Each empty wiki practically consists of these 2 elements: 1) the database 2) the descriptor. Of course, when creating the database, some basic wiki classes are also created automatically, so you can add them to the count :) Anyway, nice experiment! Thanks for sharing! Would be nice to see more of these on XWiki's features. Cheers, Eduard On Fri, Dec 13, 2013 at 4:19 PM, Jean SIMARD <[email protected]> wrote:
Hi,
I'll probably need to make it work on a MySQL for the final project but I keep MariaDB and Percona (I didn't know this one) in mind for other projects, thanks :-)

If you wanna test only XWiki, you should consider using MariaDB or even Percona instead of MySQL (so you can lower your chance being limited by database).
MariaDB and Percona both uses XtraDB (improved InnoDB by Percona), but Percona should be more "stable" in such stress tests.

Hi,
I didn't look well but I can say one thing. In the first method, when the around-250 subwikis are reached, the log is displaying errors for the next few minutes without stopping. As discussed with Thomas, we may think this is OutOfMemory error due to HSQLDB but it's probably not because of the second method that show that I can create more than 600 subwikis (the second method is more likely to be an OutOfMemory error looking the time evolution, I really should have look more carefully the logs!). I may try later on a MySQL server.
Thanks, -- Jean

Hi,
Good initiative. Have you checked the logs? Are you sure the database (HSQLDB here) is not the problem? Perhaps you'll want to run the same tests with a more robust database, like postgreSQL or even MySQL ?
Have fun!

Hi,
I need to create a lot of subwikis in a XWiki instance (5.3-milestone-2) for a project and was interested in the possibilities and limits of XWiki. I tried to make a basic stress test to evaluate a maximum number of subwikis that XWiki can handle. I wrote a small report and provide files used on this link:
http://hole.tuziwo.info/stress-test-xwiki-for-subwikis-creation.html
I'll be happy to have feedback on that. For example, I would like
to
know if my first method do something bad or if this is a possible bug in XWiki. If this is a bug, I hope this can be improved since I think that I will need more than 1000 subwikis in my project.
Hope this helps. Sincerely, -- Jean
